Here, enter the slot number of the CP in the partner station via which the connection will be
established.
Frame memory
Activate the option for enabling inter-station communication.
The frames are stored in the send buffer (frame memory) of the CP if the connection is
disturbed. Note that the capacity of the frame memory is shared by all communications
partners.
Access ID
The access ID displayed here is formed from the hexadecimal values of project number,
station number and slot. The parameter of the type DWORD is allocated as follows:
● Bits 0 - 7: Slot

● Partner monitoring time
If the CP does not receive a sign of life from the communications partner within the
configured time, the CP interprets this as a fault/error on the partner. The CP aborts the
connection and attempts to re-establish it.
If you enter 0, the function is deactivated.
● DNP3 level
Only for DNP3
Indicates the DNP3 implementation level supported by the CP
In the DNP3 specification, various levels of protocol conformity are and they describe the
supported range of functions (subset) of a master or a station. These levels
(implementation levels) are known as "DNP3 Application Layer protocol Level" and
abbreviated with DNP3-L1 to DNP3-L4.
For the communication between the CP and the master, the DNP3 level supported by the
master must be known.
The selection of the level used by the DNP3 CP which must correspond to that of the
connected master is set separately in STEP 7 for each individual communications partner
(DNP3 master).
